Answer:

1.38 * 10^ -2

Step-by-step explanation:

.0138

We need 1 number to the left of the decimal

1.38 * 10^ something

We moved it 2 places to the right, that means our exponent is -2.  If we had moved it to the left, our exponent would have been positive

1.38 * 10^ -2

A population of beetles are growing according to a linear growth model. The initial population (week 0) is
klemol [59]

9514 1404 393

Answer:

  18 weeks

Step-by-step explanation:

We are given the (time, population) pairs (0, 5) and (7, 47). With these values, we can use the two-point form of the equation of a line to write the equation of the linear model.

  p = (p2 -p1)/(t2 -t1)(t -t1) +p1

  p = (47 -5)/(7 -0)(t -0) +5

  p = 6t +5 . . . . . the linear model matching the given points.

For p = 113, the time (number of weeks) is ...

  113 = 6t +5

  108 = 6t . . . . . . subtract 5

  18 = t . . . . . . . . . divide by 6

After 18 weeks, the beetle population will reach 113.
